Healthy and sustainable intensification of aquaculture is a current trend in aquaculture development. The scale of cultivation will grow bigger and bigger. Automatic control and mechanization are the main requirements to support activities that will become increasingly complex. Water resources and the environment are of great concern. In essence, modern aquaculture has the following characteristics: intensive, high productivity, automatic operation, controlled facilities, and safe and environmentally friendly.
The application of digital technology in an effort to help optimize the shrimp culture process is currently being offered by many start-up companies. With various advantages, they offer tools for monitoring water quality and fish or shrimp health in real time. Apart from that, this application is also able to provide suggestions or warnings if culture parameters are found to be less than optimal. These capabilities can of course be obtained by buying it or renting it.
However, there are also open-source applications that can be used to build your own smart aquaculture and store the data on your own server rather than on the service provider’s server. One example is Home Assistant (www.esphome.io).
As a result of trials carried out at BPBAP Situbondo, it was possible to create three sensor nodes. The first sensor node is for monitoring water quality (DO, pH, and water temperature), the second node is for monitoring environmental conditions (air temperature, air humidity, rainfall, and wind direction and speed), and the third is the cultivation machine sensor node. such as windmills, pumps and automatic feeders. All sensor nodes can work and send sensor reading data to the controller. And the controller can receive data sent by sensors, store and display the data. Apart from being able to access the controller via a local network, it can also be accessed via the internet network. The thing that needs to be considered is the performance of the sensor, where it is necessary to calibrate.
